Wests Tigers fullback James Tedesco insists he has moved on from his Canberra Raiders contract backflip, but admitted ''there may be some sledging'' when he faces the club he turned down on Saturday.

But Raiders prop Paul Vaughan quashed suggestions they will verbally target his close friend, adamant ending their form slump is their sole focus.

Tedesco rocked the NRL when he used the round-13 cooling off rule to renege on a three-year deal with Canberra last month, opting to stay at the Tigers for far less money, and knows the spotlight will be on him at Campbelltown.

"There may be a bit of sledging. You have to expect that in games these days anyway,'' he said.

"Playing the Raiders, I'm not really worried about it to be honest, it's another game.''

The 21-year-old revealed he temporarily deleted Twitter to avoid backlash from disgruntled fans, and knows the spotlight will be on him at Campbelltown Stadium.

"I deleted Twitter for a good two weeks so I didn't have to put up with that kind of stuff. But to be honest, there really wasn't that much backlash,'' he said.

"Obviously Raiders fans will be disappointed and a bit angry, you have to expect some frustration from them.

"Personally, that stuff doesn't bother me, I had to do what's best for me.''

Tedesco rated phoning Raiders coach Ricky Stuart to inform him of his change of heart the ''most nervous situation I've been in.''

He also found it difficult to tell Vaughan, with whom he struck up a close bond as Italian teammates at last year's World Cup.

"I spoke to Vaughany after I made the decision and told him 'sorry mate, I just couldn't do it'. He was supportive,'' he said.

"It's tough to leave the place where you came through with your footy and most players understand the situation.''

Tedesco backed the controversial round 13 rule, which has been under fire since Raiders back-rower Josh Papalii reneged on a contract he signed with Parramatta last year.

"It's probably good people aren't rushed into decisions, you've got time to think it through and go through all the scenarios,'' he said. "To be honest, I didn't really know about the rule, hopefully I don't have to worry about it again.

"It's exciting for the game a lot of players are staying loyal to their clubs.

"The opportunity's there to make as much money as you can because it [football] doesn't last forever, but it's not the only thing to worry about.

"It's about playing with your mates, where you're most happy and where you think your footy will most benefit.''

Vaughan returns to Canberra's line-up against the Tigers after missing Friday night's home loss to Canterbury through a one-match ban for a crusher tackle.

Asked if the Raiders players would direct some ribbing Tedesco's way, Vaughan said they will be concentrating on a win after losing six of their past seven games.

"It's just like any other footy game, you can't worry about that stuff too much,'' he said.

"We're not going to go out there and specifically target him, it's probably not the right thing to do.

"We have to play footy, we need a win.

"It's unfortunate he didn't come, it'll be an interesting game this weekend.''

While disappointed they won't be teammates next year, Vaughan backed Tedesco's decision and said there would be little point coming to the Raiders if he was not fully committed.

"We were chatting and touching base when he was going through the contract stuff, and I told him a bit about Canberra,'' Vaughan said.

"When he told me he wasn't going to go through with it, I gave him a bit of support and said to do whatever's best for you.

"You want everyone here at the club to be 100 per cent committed. If anyone's second guessing themselves, it's probably best they don't come.

"I'm a bit the same, I'd find it really hard to leave here too and at the end of the day I think he made the right choice.''
